Need more power

[patarol]

I`m planing to add som more power on the bike this winter, TDR racing is where i buy my stuff and he rekomended to get:

 

CPI pipes.

Cheeta 392 cubs. (i dont want to change crank open engine)

34-35mm carbs.

 

Wil this give me a lot more power then i have to day? se my mods.

and can some explain what a air stricke carb is???

 

are the Cheeta a good choice?

 

Thanks for all coments!

you need to do some research before yu go buying all this... theres alot more to getting power then tossing a bigger motor in the frame and going... depending on what type of riding your doning will determine what motor and porting, pipes carb suspension... everything...

 

once you start adding power you need to upgrade your clutch and suspension if you have not done it already... if your "guy" has told you this is the way to go... id say find a new guy to do business with! he should be filling you in more then just selling you shit. you need the whole packge... the parts, the knolwedge, the understanding.... if he isnt providing you with those things ... he doesnt have your best interest in mind, he simply has your wallet in his mind

I just asked him about the cheetas and he rekomended the other stuf to get the best power of the sheetas, or wil my 28mm mikuni and FMF fatty pipes work good enough with the 392 cheeta? i ride most forest roads and fields. want som good mid power to. Already got the better clutch EBC.

 

 

do you men the CPI and cheetas is shit parts? I understand that most ride cheetas vs T-rex....?

It may be best to consider baby steps , meaning using your mods with a port job and upgrading pipes .That will be a good power jump over what you have and be the least expensive .droping a cub in your banshees set up would be like droping a built small block chevy in a little toyota and keeping the little 1" exhuast and running a tiny air cleaner made for the 4 banger that was in it . oh and keeping stock axels lol. cheetah cubs are top notch technology imo and i would do a lot of reserch like bansh-eman said , i wouldnt build that motor without everything else to go with it , your gona drop 2plus k in it and still need stuff . port it and upgrade pipes , step one :thumbsup:

I am building the same motor and was trying to go at it like you are. I was going to try stock carbs, Toomey T6, didnt want to split the cases to weld the crank and wanted to run pump gas.

 

The more research and learning I did, I found that just wasnt going to be the right setup and I was putting a couple thousand dollars worth of parts in jeopardy by not welding the crank.

 

You can still build a cub. I am and a lot of people told me not to but its what I wanted. Its just gonna cost a little more than you see on paper I gaurantee that.

 

I ended up with a 392 cub, 35pwk's, shearer inframes, +6 swinger, splitting the cases, welded crank, and race gas.

 

I would have built a 421 but I didnt want to buy a new crank when my stock one is in perfect shape.

 

Its great to hear what you want to hear when you call or research the motor you want to build. But when 9 out of 10 people say, chances are it will run but its going to make horrible power and your wasting a lot of money trying to put 80-90hp capable cylinders on a 45hp capable bike/parts it just isnt going to be what you want.

 

With all that being said....hopefully my 392 cub will be together by the first or second week of October and I can go see if a cub is everything its cracked up to be.

 

Just remember, build what you want. Make yourself happy. If it runs good, awesome, if it doesnt then you will just end up spending more to make it right.

Tony is a very good bike builder. But he builds mostly racing bikes (banshees) and wave runners. Hes going to recommend alot of expensive parts. He doesnt just have a reputation with banshee riders, he has a rep with everyone in the area. Good people. I dont think he like a little of this a little of that,... its do you wanna go fast or not !? :cool:

[patarol]

Wel the problem is that i live in Norway and there are no one that do port work that i know of. I think i`m the only one here with a Banshee like mine. Not many banshee riders in Norway. But plenty of 4-strokers and i love to beat them So i`m willing to sbend the $$ on the sheeta with carbs and CPI pips if this is a good and lasting setup?

your probably better of putting a 4mm stroker in there and bigger carbs and porting it for your riding stlye.Then if you decide you really wanna fly get a Cub cylinder.But you aint going to like a stock stroke cub for trails

[letsgetthisdone]

i'd say port your stock jugs, get 30mm carbs, get a coolhead, and have your stock crank tured and welded.

 

 

call Jeff at F.A.S.T. racing, his website is www,farmandsandtoys.com

 

he will hook you a port job thats gonna give you power where you want it to be. that cheetah cub is gonna make no bottom end, very little if any midrange than its gonna hit hard as fuck when it hits about 8,000 rpms, then your gonna need to shift when it hits 10,500 rpms....not a fun trail motor imo...that narrow powerband is going to very difficult to keep on the pipe.

 

 

not to mention you will need a lockup clutch and an override tranyy if you go with the cub..

[patarol]

Ok, thats enough negativ about that setup, i drop the cheeta then. A 4mil crank wil need porting and new pistons and spacers???? dont know mutch about this stroker stuff..... how mutch power wil it make??

[flattrakker]

you need to slow down and start with the basics.. like opening up the air intake... pipes.. most any piped/filtered banshee will run with any 4 stroke.. your rushing into things and your bill will add up VERY fast... id say start with a little more research by talking to a reputable builder..

Like i wrote there is non two stroke builders her in Norway that can do the port jobs you can get over there, so i have to buy bolt on things! I did a clean up port my self and added the things listed below. it runs great but i`d like som more power and thought the cheetas 392 was the next step. I already packed the stock jugs with all you can get xept for the porting. the power gain vs the stock is a big diferens!

[letsgetthisdone]

if you get a 4mil long rod crank. you will need 795 series wiseco pistons to compensate for the long rod, your cylinders ported for the 4 mil crank, and coolhead with domes for the stroker, no spacers required..

wel there we go again, cant get that port job don her in Norway. I see FMF have som sylinders with power walves, maby thos wil give me the power i want? anyone tryed them??

[RZBansheeMan]

Call Jeff at FAST........ he will give you damn good advice !!!, don't do cubs unless you are a drag racer (300 ft distances or 100 yds - whatever you want to call it) the cubs are not trail friendly unless you like aiming at trees and hitting them at 80 + mph...........most likely a "dune" / "play" port will satisfy your needs.

 

Power wise your looking at doubling your stock power with a dune port, 4 mm stroker, V-Force 3 reeds, 33 mm PWK carbs and T-5 pipes........ think about it, 36 hp to a solid 75 hp ..........it will give you a "hard on" the size of the Eiffel Tower, and make the 4 strokers be envious, especially if you use the stock head (with custom dome cutting) and tell them you have a stock Banshee with only pipes, reeds and carbs..........
